Recently, while researching cross-border payments, I found that many people still have a pretty vague understanding of the concept of offshore Renminbi. In fact, this involves two completely different exchange-rate systems at home and abroad, and it’s well worth understanding them.

Simply put, the trading logic of Renminbi is completely different inside China and outside China. Onshore Renminbi (CNY) is the version traded within mainland China, tightly controlled by the central bank, with clearly defined limits on exchange-rate fluctuations—its daily floating band is ±2%. The participants are mainly domestic banks, enterprises, and individuals, and it is used for everyday economic settlements. Offshore Renminbi (CNH) is the version traded in places such as Hong Kong, London, and Singapore. There is no direct intervention by the central bank, and the exchange rate is determined entirely by international market supply and demand. The participants are offshore banks, investment funds, and multinational corporations, and it is mainly used for cross-border investment and international trade.

Why split into two markets? The main reason is historical. China’s capital account has not been fully opened yet. On the one hand, it is meant to isolate offshore risks; on the other hand, it also wants to promote the internationalization of the Renminbi. So two parallel markets were set up. Onshore CNY helps safeguard domestic financial stability, while offshore Renminbi makes it easier for overseas holders of Renminbi to reduce cross-border transaction costs—for example, “Belt and Road” projects often use CNH for settlement.

Actually, this approach is not unique to China. The Indian rupee, Brazil’s real, Malaysia’s ringgit, and South Korea’s won all have similar distinctions. In these countries, their offshore markets typically trade through non-deliverable forward markets. The core purpose of this design is to control capital flows and prevent domestic economic development from being hit by volatility in international markets.

For ordinary people, the difference between these two markets directly affects currency exchange, investing, and exchange-rate risk. Individuals in the mainland can only exchange CNY equivalent to up to $50,000 USD per year, and they must declare the purpose, but opening a bank account in Hong Kong and using CNH is basically without such restrictions. In terms of investment, onshore CNY is used to buy A-shares and domestic wealth-management products, while offshore Renminbi is used to buy Hong Kong stocks or “Dim Sum” bonds. If importers pay in CNH, they have to bear greater exchange-rate risk, but arbitrageurs can take advantage of the price spread between CNY and CNH to profit.

For example, a Shanghai export company receives $1 million USD. When converting it into RMB domestically, the process is subject to the central bank’s controls—while converting it through an offshore settlement account in Hong Kong is based on the CNH exchange rate. Depending on fluctuations, the company may earn more or less, because CNH is more volatile. When the Federal Reserve raises interest rates, CNH often depreciates quickly as international capital sells off Renminbi, but CNY depreciates much less due to central bank intervention.

Looking ahead, as the internationalization of the Renminbi continues—especially with the expansion of cross-border use of digital Renminbi—the exchange-rate spread between the two markets will gradually narrow. However, CNH’s exchange rate will still be more sensitive and more easily affected by international events, such as U.S.-China frictions, while CNY still focuses mainly on “maintaining stability.” The central bank’s toolkit is quite extensive, and counter-cyclical factors and other measures can be used at any time.

In the end, CNY is like the “domestic version” of the Renminbi: safe, but limited. Offshore Renminbi is the “international version”: freer, but more volatile. Only by turning both wheels together can the Renminbi be pushed onto the global stage. If you’re engaged in cross-border business or have overseas investment plans, it’s still very necessary to understand this difference.
